RMH Consumption

I'm in an odd situation - too much wood.

Let me explain. Over the past couple decades, we've lost a lot of trees to storms.
There are a couple very large piles of branches, perhaps 8-10 feet high and 80 feet end to end.
The tree trunks were turned into lumber and most of the flitches (unusable slabs off the outside) are tossed in a couple pretty large stacks as well.
I've been cutting and burning what I can and even had a big winter bonfire a couple years ago. But the piles haven't diminished much.
No one else here wants to burn spruce, much less 2" branches that have been sitting for years.

Hugels are the obvious answer, but I don't have any space with sunshine.
And since the forest is so thick and the soil so thin, taking down a few trees to make that space would domino a ton of other trees without much wind.

So I think I need to build, at least temporarily, a large RMH outside.
I wonder if a "shorty" would work - but my hope is to burn off as much of this junk wood as I can, without adding a ton of crap to the atmosphere.
I know this is contrary to the goals of RMH, but what is the "hungriest" low emissions wood burner?
And do any work well without a door?

Thanks

Sorry, I don't know about a RMH to consume wood but her are some other ideas.  Sorry it's not what you're asking:

Maple syrup producers might want your wood.

Some companies chip up forestry waste and turn it into electricity.  Not sure how you go about getting a hold of them but that might be an option.

Burning them, just to get rid of the piles, seems like a bit of a waste but I can see how they'd be in the way.  I'd think they'd start to decompose in a few years and then you could get someone with a tracked machine to drive over them to pack them down and they'd decompose even faster.

Hey Randy, A terrible problem to have!

I don't think A Shorty is the correct burner, much too casual a burn.
You want a first-gen batchbox... OR

Here's an idea!
With slash piles like that, all you really need is a ten-foot section of large culvert.
Using steel cables, suspend the culvert over your slash pile like a huge riser,
Make sure there are no low-flying aircraft passing by...
Light her off and stand back, they will see your slash pile rocket from the space station!

This really does work, but hanging the culvert can be a problem...

Unfortunately, the quality of what is there is not good enough that anyone would invest enough to come and get it.

I'd really like to shred the whole shebang and have wood chips for years. But that seems like that's a real waste of petrol.

Thomas - I'm curious, do you think I need to insulate that culvert riser?

I could make a lot of biochar with that much wood and a trench...

What Trace said. Dig a pit or a trench and make lots of biochar. Then you'll have a gift that keeps on giving.

Please forgive the ignorance - what do I do with biochar?

And can you steer me to any links on best techniques?

Have a look at this:

case study of pit burning for biochar

and you'll see how we processed about 30 cubic meters of pine slash one winter's day.

As far as the uses go, it's great for soils, animal health, water quality, even construction material. Lots of threads on this site to pore through....
